New York Jets WR Greg Salas had two difficult catches during practice Tuesday, July 29, and RB Daryl Richardson made several big runs. Dom Cosentino of The Star-Ledger believes both players have improved their chances of making the roster during training camp.

New York Jets RB Daryl Richardson (toe) will have to regain the speed and explosiveness that he showed as a rookie in 2012 if he is going to make the roster, according ESPNNewYork.com's Rich Cimini. Richardson's 2013 season was ruined by a turf-toe injury.

Fantasy Tip: Powell, Green and Daryl Richardson are fighting for touches behind Chris Johnson and Chris Ivory, who are both dealing with injuries. Powell has late-round appeal, while Green and Richardson are best left to the waiver wire, unless either leapfrog Powell on the depth chart.

Fantasy Tip: The Jets already have a very crowded backfield with Chris Johnson, Bilal Powell and Chris Ivory, so Richardson will do nothing more than provide depth at the position. He shouldn't be drafted in most leagues.

The St. Louis Rams want RB Daryl Richardson (toe) to stay off his foot during the offseason and let it heal after a turf toe injury in the 2013 season opener significantly impacted his performance throughout the year. According to a source close to Richardson, he will not need to undergo surgery.

St. Louis Rams general manager Les Snead said he believes RB Daryl Richardson will be able to compete for playing time next season after struggling with injuries this season. "We've all seen what he can do. Some injuries derailed him a little bit. ... What you like about the whole thing is as you bring in more players, as we all grow here, there's more competition," Snead said. Richardson could be a change-of-pace back for the team but will need to improve his pass catching and pass protection.

St. Louis Rams RB Daryl Richardson (thigh) did not participate in practice Friday, Dec. 27, and is listed as doubtful for Week 17. FS T.J. McDonald (illness) did not participate in practice and is listed as questionable. DE Chris Long (thigh) fully participated in practice and is listed as probable.

St. Louis Rams RB Zac Stacy (ankle) was limited during practice Friday, Nov. 1, and is listed as questionable for Week 9.

Fantasy Tip: Owners will have to wait until the inactive list to see if he will be on the field for the game. Stacy should be considered a low-end starting running back or flex option if he is able to play. With Daryl Richardson and Benny Cunningham also being questionable, Isaiah Pead could have a bigger role in the offense but should not be in starting lineups this week.

Updating a previous report, St. Louis Rams RB Zac Stacy (ankle) sprained his ankle in the team's Week 8 game Monday, Oct. 28, and he was not on the field for the club's final drive of the night. Stacy went back on the field for the final play of the game and was split out wide instead of being used in the backfield.

Fantasy Tip: It's unclear how severe Stacy's ankle injury is at this time, so check back for updates. If he's forced to miss Week 9 against the Tennessee Titans, Daryl Richardson would likely see the majority of touches.

Fantasy Tip: Stacy is the "lead" back for the Rams for the second straight week, but Jeff Fisher will likely keep Daryl Richardson and maybe Isaiah Pead involved somehow. St. Louis' offense hasn't been consistent enough to get excited about Stacy. He's a flex play in deeper leagues.

St. Louis Rams RB Zac Stacy made the start in Week 5 against the Jacksonville Jaguars, and he carried 14 times for 78 yards. He was also targeted once, but did not have any receptions. Stacy split carried with RB Daryl Richardson, who ran 13 times for just 48 yards, and he too was targeted once with no receptions.

Fantasy Tip: It appears to be a timeshare in St. Louis between Stacy and Richardson, and it appears Stacy has a little more potential. Both should only be considered as RB3s or flex plays going forward.

St. Louis Rams head coach Jeff Fisher said the team will probably go with a committee approach at running back in Week 5 against the Jacksonville Jaguars, and RB Zac Stacy could receive his chance after RBs Daryl Richardson, Isaiah Pead and Benny Cunningham haven't been very productive. "I think Zac's done a really good job since he's been here," QB Sam Bradford said. "He's a very talented runner. He's a powerful guy. He's got great vision. He makes cuts in the hole that are quick and decisive, so I'm excited to see him out there." Stacy has only one carry for four yards on the season against the Arizona Cardinals in Week 1. He was inactive in Weeks 2 and 3. The rest of the team's running backs haven't been good in pass protection through four weeks, and although he hasn't proven himself in the NFL yet, Stacy had a reputation as a good pass blocker coming out of college.

Fantasy Tip: Many expect Cunningham to be the next man up in the Rams backfield, but it could easily be Stacy, as well. He's the cheaper option off the waiver wire this week. It wouldn't hurt to stash him and see how this plays out this weekend.

St. Louis Rams head coach Jeff Fisher wouldn't say who would be the starting running back this weekend against the Jacksonville Jaguars after RB Daryl Richardson hinted that he wouldn't be starting in Week 5. The Rams are currently last in the league in rushing, averaging just over 47 yards per game. Richardson is averaging a measly 2.7 yards per carry. "We have just had one day of practice and all the backs got to participate in practice, so we've got different things for different style of runners," Fisher said.

Fantasy Tip: Unfortunately for fantasy purposes, we may not know much about the running back rotation against the Jacksonville Jaguars until the game is actually played. This makes Richardson, Isaiah Pead, Zac Stacy and Benny Cunningham all very tough to start. It may be best to stay away from the situation until we get a better feel for it.

Fantasy Tip: This puts more uncertainty around the running back position in St. Louis. Will it be Richardson, Benny Cunningham or Zac Stacywho receives the majority of the carries in Week 5? It's really anyone's guess right now, but we wouldn't be surprised to see Cunningham take over the role, at least this week. Scoop him up if you own Richardson or are desperate for a running back with upside.

Fantasy Tip: The Rams used a combination of Benny Cunningham and Zac Stacy last week, albeit very ineffectively. Isaiah Pead was a surprise inactive, and we're not sure if he'll be active this week. This situation is a mess, but they do have a very good matchup against the Jacksonville Jaguars this week. Stay tuned for more details later in the week.

St. Louis Rams RB Daryl Richardson (foot) practiced on a limited basis Monday, Sept. 23, and he expects to play in Week 4 versus the San Francisco 49ers Thursday, Sept. 26. He leads the team with 30 carries and 98 yards in three weeks despite playing just two snaps in Week 3 before aggravating his injury.

Fantasy Tip: San Fran has been surprisingly vulnerable against the run this year, so Richardson, assuming he plays a full game, is a sneaky good play this week. To keep him fresh, Isaiah Pead may see more work than usual, however.

St. Louis Rams RBs Isaiah Pead and Benny Cunningham split the carries in the Week 3 game against the Dallas Cowboys with RB Daryl Richardson (foot) leaving the game after just one play. However, neither Pead nor Cunningham did much. Pead carried six times for 20 yards, while adding seven receptions and 43 yards. Cunningham had four carries for 16 yards, while adding one catch for six yards.

Fantasy Tip: It's uncertain if Richardson will be ready to go in Week 4. If not, Pead, Cunningham and perhaps rookie Zac Stacy could be in line for more work.
